On initial departure while joining the formation, the pilot felt an unusual vibration in the airframe. The pilot checked the engine instruments and determined that the oil temperature was high. After clearing the formation and turning the airplane back toward the airport, the engine stopped producing power. The airplane descended, was landed gear up in a clearing, and was substantially damaged during the landing. The cause of the high oil temperature could not be determined. ## Factual narrative The pilot departed as number two of a three airplane formation.
